SILAS R. DIVINE, OF LOCH SHELDRAKE, NEW YORK, ASSIGNOR TO THE BEND ROCKPOWDER COMPANY, OF NEW JERSEY.

EXPLOSIVE COMPOUND.

SPECIFICATION forming part of Letters Patent No. 289,756, dated December4, 1883, Application filed July 23, 1883. (No specimens.)

To all whom it may concern.-

Be it knownv that I, SILAS R. DIVINE, of- Loeh Sheldrake, Sullivancounty, State of New York, and a citizen of the United States, have 5invented an Improved Explosive Compound, of which the following is afull, clear, and exact description.

The object of my invention is to provide an explosive compound forblasting and other 10 purposes, the ingredients of which can be handledand transported separately without hazard from explosion, and can beunited by the consumer to form the explosive at the time when and theplace where its use is desired.

My invent-ion consists of an explosive compound composed of twoingredients, the one a solid-such as chlorate of potash in a crushed orpowdered state-and the other a liquid, such as the heavy oil ofcoal-tar, which is 20 commonly called dead-oil. These ingredients arecombined to form the explosive-by allowing the solid ingredient to.absorb the liquid ingredient; and this can be doneby the workman orminer at the place and when the 2 5 explosive is desired for use. Thetheoretical proportions in which the said ingredients combineefi'ectively to constitute my explosive compound are about seven andone-half parts of chlorate of potash to one part of dead-oil.

0 The exact theoretical proportions need not, however, be strictlyadhered to, as avariat-ion somewhat therefrom will still yield an.effective explosive.

Perchlorate or permanganate of potash may be employed as the solidingredient-of the U compound, and other fluid hydrocarbons which arepractically non-volatile in a free state at ordinary temperatures-saysuch as have a boiling-point above about 300 Fahrenheit-may be used asthe liquid ingredient.

The ingredients of my improved explosive compound may, if desired, bemixed in Uh;- proper proportions in a convenient receptacle.

In Letters Patent No. 243,432, dated June 28, 1883, I have describedamcxplosive com- 5 pound of this character co1uposed of a solidingredient-such as chlorateot' potashand a liquid ingredient-uch asnitro-benzolc, or other liquid nitro compound-and therefore I do notintend to claimherein acompoundcomposed of such named ingredients.

\Vhat I claim as myinvention, and desireto secure by Letters Patenthereunder, is-

The explosive compound herein described,

which consists of a solid in gr'edient-as chlorate .5 5

of potash-and a liquid ingredient-as the heavy oil of coal-tar(dead-oil)-mechauically united substantially in the proportions and asand for the purposes setforth.
